repair

1.注意下面两句意思不同：

• The house is in repair.（这房子是完好的。）
• The house is under repair.（这房子正在修理。）

2.in repair（完好的）=in good repair，out of repair（不完好的、失修的）=in bad repair。注意good和bad的前面没有a。

3.repairs作“修理工程，修理工作”解。例如：This house needs a lot of repairs before anyone can live in it.和The tenant has to do all the repairs.不可说a repair。

4.上面一条说不可说a repair。The breach（感情上的破裂）seems to have been repaired, but it was only a brief repair里用a，指“一次”或“一件”。
